[Summary]Our tendency toward the gospel is more personal (internal) than relational (external). However, when the gospel works in us, it always works through us as well. Therefore, the gospel is not only internal and personal, but also external and relational. As the gospel changes our hearts and motivation in regard of our personal relationship with God, it also motivates and compels us to extend our love to our neighbors. It is common that Christians feel that the mission work (serving others, sharing the gospe and etc.) is a mandatory duty rather than a joyful reaction to God's grace. However, when the gospel works in us, it reveals our sins laid behind our unwilling to serve others and gives us the promises which is enough to renew our hearts.
